PRINTER/S ANGLE-FURNITURE UNIT.

Application filed August 6, 1928. Serial No. 297,618.

My present invention has for its object to provide printers angle furniture in a two-part unit of very simple and inexpensive construction for convenience in quickly 5 and easily locking printers forms in a chase at various angles. y

More particularly, it is my object to provide such a two-part furniture unit comprising respectively an element lsubstantial- 1y triangular in outline, having two faces arrange at right angles to each other and havingin the hypotenuse of the triangle a concave-faced` portion, curved, substantially on the arc of a true circle. The other element of the unit is a member made substantially in the form of a half of a circular disc of substantial thickness with its .curved face adapted to fit the concave face in the lirst element.

With these a'nd other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my angle furniture unit, whereby the objects contemplated are attained, as

hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:`

Figu chase with a lock-up for a form therein employing my improved furniture.

. Figure 2 is a detail, vertical, sectional view taken-on the line 3--3 of Figure 1, showing in section both elements of m furniture unit and a quoin of standar' construction; and f Figure 3 is a erspective view of the two elements of my rniture unit.

In the drawings herewith, I have used the reference numeral 10 to indicate generally a 40 printers chase. Received within the chase is an ordinary rectangular form 12 arranged with its axis at a substantial angle withrelation to the inner walls of' the chase.

It isa difficult matter to lock such a form at such an an le in the chase, so that it will not slip undger the conditions ordinarily found when the form is used in a printing press. Yet it becomes necessary in the printing industry to lock forms in chases at 4 50 a great variety of angles.

For purposes of illustration, I have shown the form 12 used with a plurality of my furniture units.

It will be noted that the usual furniture (not now referring to my particular units) re -1 is a plan view of a printers comprised of blocks 14, 15, 16, 17, 18, 19, 20 and 21 is usedfor building out from the walls of the chase. y My improved unit comprises two elements lndicated in Figure 3 by the reference characters A and B.

The furniture unit element A is in the form of a block substantially triangular in outline with two faces 22- and 24 arranged 1n planes at right angles to each other. The face of the element A, which is, as one might say 1n the hypotenuse of the triangle, is curved as indicated at 26 on the curvature of a circle. For instance, the arc taken any place 1n the horizontal plane on the element vA would extend from near the face 22 to near the face 24, as shown in Figure 3.

The other element of the unit comprises a block B in the form of a half of a circular disc of the same height or thickness as the block A. y l v The curved face ofthe element B fits the face 26 of the element A.

The to of the element A may be provided with gra uation marks 27 and the top of the element'Bv may be provided with an indicating arrow 29 midway of the length of itsl curved face. y

In Figure '1, I have shown several of my units arranged in different positions to s how the. various ways in which the unit can be employed. t

For instance vat the 'upper right-hand corner'of Figure 1, I have shown the member A of one of the units arranged with one face against the furniture member 21 and the other member against the side wall of the chase. The flat, vertical face of the unit member B lits against the end of the form 12, and the curved faces of the mem- 95 bers A and B fit together, as shown. The unit now under consideration, I have indicated generally by the reference character I have indicated another unit at b with the member B arranged with its flat vertical 100 face against the face of a rectangular piece of printers furniture member 30 and with the member A arranged with one face against the furniture member 20 and the other' against an ordinary quoin 28 arranged 105 between the element A and the furniture member 19.

At o, I have shown another one of my elements, with the member A in the corner formed by the wall of the chase, and the fur- 11o niture membei` 18, and with a quoin 28 interposed between the member element B and the furniture member 30.

At the opposite end of the form from the unit shown at a is a unit indicated at d, showing a slightly different arrangement in which my unit may be used. Adjacent the side of the form opposite the member 3() is a similar furniture member 30a.

One of my units as shown at e, together with another quoin 28 is arranged between the furniture member 30a and the corner formed by the furniture members 15 and 16. f

As shown at f, still another of my units is arranged near the opposite end of the member 30a between that member, the side wall of the chase, and the end of the member 14.

A quoin 28 is interposed between the element A and the member 111.

lVith this style of furniture unit, there is provided a printers lock-up, by which much time is saved in locking diagonal forms in a chase. The time necessary for securing accurate registration is considerably reduced.

My improved unit is thick enough and sturdy enough to permit the rigid locking of the form in any possible position.

The form can be locked at any angle with relation to the walls of the chase without any tendency of the unit members A and B to slip or rotate with relation to each other.

The units are so arran ed that if the unit B is rotated slightly wlth relation to the unit A, there remains ample bearing surface for taking pressure directly at right angles to the side face or edge of the form. Thus it is convenient to lock a form arranged at an angle to the walls of the chase by means of these units, together with other furniture betweenV the units and the sides of the chase with one or more quoins for adjustment.

My angle furniture unit may be placed on all four sides of a form, but quoins are actually needed only on two sides. If uoins are used on all four sides, this will facilitate easy and speedy securing of accurate register, since any quoin can beadjusted by expanding or contracting, when used with my units, and the parts can be quickly adjusted to proper position.

The graduations on the elements will indicate the movement of the form and thus eliminate guess work.

Itwill be noted that my improved angle furniture unit will function equally Well with the quoin in front or behind the unit.

The advantage o'f placing the quoin behind the unit is in bringing the type form closer to the rim of the chase when necessary.

I prefer to use the Notting quoin in conjunction with my angle furniture as it allows free action and has a. straight forward shove without any right or left give. This is important in an angle form for registering color work and so forth.

I claim as my invention:

1. A printers angle furniture unit com. prising a pair of elements, one of Said ele ments comprising a block of substantial thickness, substantially triangular in outW line with two faces arranged in lanes at right angles to each other, and a t ird face on the hypotenuse vside of the triangle curved on the arc of a circle, and a second element in the form of a portion of a disc of substantial thickne having a curved face corresponding with the curved face of the first unit.

2. A printers angle furniture unit comprising a pair of elements, kone of said ele-A ments comprising a block of substantial thickness, substantially triangular in outline with two faces arranged in planes at right angles to each other, and a third face on the hypotenuse side of the triangle curved on the arc of a circle, and a second element in the form of a portion of a disc of substantial thickness having a curved face corresponding with the curved face of the first unit, one of said units havin on its top surface graduation marks and t e other having an indicating mark.
